[jira] [Created] (KAFKA-9792) Improve sticky task assignment for previous active tasks

Sophie Blee-Goldman created KAFKA-9792:
------------------------------------------

             Summary: Improve sticky task assignment for previous active tasks
                 Key: KAFKA-9792
                 URL: https://issues.apache.org/jira/browse/KAFKA-9792
             Project: Kafka
          Issue Type: Improvement
          Components: streams
            Reporter: Sophie Blee-Goldman
            Assignee: Sophie Blee-Goldman


Due to the way the client quota is computed, we may end up passing over a client that is not yet full. This can cause us to “miss” the client while attempting to assign active tasks to their previous owners, and ultimately forcing an active task _away_ from its previous client.

It’s not quite a bug, but it’s definitely sub-optimal behavior and can cause unnecessary task shuffling. It also makes the assignment harder to predict/debug
